DAVID S. KENNEDY, OF BROOKLYN, NEW YORK, ASSIGNOR TO MERGENTHALER LIND- TYPE COMPANY, A CORPORATION OF NEW YORK.

LINE-CASTING MACHINE.

To a ill/min. it may concern Be it known that I, Davin S. KENNEDY, of the borough of Brooklyn, county of Kings, and State of New York, have invented a new and useful Improvement in Line- Casting Machines, of which the following is a specification.

My invention has reference to line casting machines of the l\[ergenthaler type, such as represented in Letters Patent of the United States No. 436,532 and kindred machines, wherein the slug of printing bars are cast in a mold, are delivered therefrom by an ejector, and carried edgewise between two parallel trimming knives into the receiving galley. In the use of these machines it is found that the metal chips or shavings removed from the slug by the knives are liable to cling to the edges of the latter, so that if permitted to remain they will be em bedded upon the printing face of the next slug. To avoid this difficulty it is customary to provide the machines with a so-called knife wiper, which travels along the edges of the knives after the delivery of each slug in order to remove the shavings. As heretofore constructed these wipers have generally been arranged to stand normally at the lower ends of the knives and to travel upward thereover in removing the shavings. It is found that when the wiper acts with this upward movement the shavings are liable to accumulate thereon and to be trans ferred to parts of the machine where their presence is objectionable.

The object of the present invention is to overcome this difficulty, and to this end it consists in a wiper arranged to stand normally at or above the upper ends of the knives and to effect the removal of the chips and shavings therefrom by a downward movement. This wiper acting on the shavings from above serves to detach them from the knives and to permit a free downward movement from the machine.

In the drawings I have shown those details of construction which I find best adapted to meet commercial conditions, but itwill be manifest to the skilled mechanic that the details may be modified without changing the principle of action or passing beyond the limits of my invention.

Figure 1 is a perspective view from the front of the mold disk, one of the trimming knives, the first elevator, and a Wiper con- Specification of Letters Patent.

Application filed. February 3, 1911.

Patented July 5, 1913. Serial No. 606,323.

structed in accordance with my invention, portions of these parts being broken away to expose other parts to view. Fig. 2 is a side elevation of the parts shown in the preceding figure. Fig. 3 is a cross section on the line 3-43 of Fig. 2.

The parts represented in the drawing, with the exception of the wiper mechanism, are those commonly employed in commercial l\[ei.'genthaler machines. These parts, and other parts not shown and foreign to my invention, may be of the ordinary or any approved construction.

Referring to the drawings, A represents a portion of the main frame, commonly known as the vise frame; B the vertical, intermittingly rotating mold wheel, having the slotted mold (l mounted therein.

1), Fig. 1 is the forward end of the ejector blade, by which the slugs cast in the mold slot are delivered in a forward direction therefrmn between the trimming knives into the receiving galley.

E-E are the two upright parallel knives between which. the slug F is delivered by the ejector l).

G is the galley located at the front of the machine to receive the upright slugs as they are delivered one after another between the knives.

II is a vertically sliding member mounted in the main frame and commonly known as the first elevator, its upper end being provided with a jaw, not shown, to sustain the line of matrices in front of the mold when the latter is in the horizontal casting position.

So far as described the parts are of the ordinary construction.

Referring now to my improvement, I rep resents the knife wiper in the form of a thin blade secured to the upper end of a rod, J, which is guided at its upper and lower ends in the frame so that it moves upward and dowmvard the wiper I will be caused to traverse the edges of the knives from end to end. The wiper rod is connected by a link, K, to an angular lever, L, mounted midway of its length in a horizontal pivot, M, on the main frame.

I is a vertical spring extending from the. main frame or other fixed support to the for ard end of the lever L, its effect being to hold the end of the lever down and thereby maintain the rod J and the wiper I in an elevated position, with the wiper at or near the upper ends of the knives and ward end extended laterally at G into the path of the latch O. The wiper stands in the position represented in Fig. 1 until after the delivery of the slug and the retreat of the ejector D.

After the casting action the elevator H rises, carrying with it the latch O, which engages theforward end of the lever L in the manner shown in Fig. 2, thereby raising the same and causing the lever, through the link K, to draw the rod J and wiper I downward until the wiper has traversed the entire length of the knives and delivered the shavings therefrom in a downward direction. The latch travels with the elevator a distance greater than that required to actuate the wiper, and as it continues its upward movement the parts assume such relations that the latch disengages from the lever, thereby releasing the wiper, which is immediately raised to its original, normal posit-ion by the spring N.

Having thus described my invention, what I claim and desire to secure by Letters Patout is:

1. 111a machine of the class described, in combination with the first elevator and the trimming knives, the vertically guided wiper, means actuated by the first elevator to give said wiper a downward stroke in relation tosaid elevator and to render the wiper active on the knives on said downward stroke, and means including an actuating spring tending independently of the 40 elevator to return said wiper to its normal position, irrespective of the movement of said elevator.

2. In a machine of the class described, in combination with the first elevator, the trimming knives, the vertically guided wiper, the actuating lever operatively connected with said wiper, the spring connected to said lever to raise the wiper, and means adapted to engage said lever when the elevator moves in one direction and to pass by said lever when the elevator moves in the opposite direction, whereby said wiper is given a downward stroke and acts on the knives on said downward stroke, and is returned to normal position independently of the elevator.

In testimony whereof I hereunto set my hand this twenty sixth day of January, 1911, in the presence of two attesting witnesses.
